    This is a list of minerals which have Wikipedia articles.. Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species.

  3. Hierarchy of precious substances - Wikipedia

    en.wikipedia.org/wiki/Hierarchy_of_precious...

    Events-sponsorship in sport or in the arts may involve (for example) silver, gold and/or platinum sponsors. Fantasy role playing games often have a hierarchy of materials, following the relative strengths of pre-modern metals, bronze, iron and steel, for example, at the lower end, and moving up through fantastic or legendary materials such as ...

  4. Noble metal - Wikipedia

    en.wikipedia.org/wiki/Noble_metal

    A galvanic series is a hierarchy of metals (or other electrically conductive materials, including composites and semimetals) that runs from noble to active, and allows one to predict how materials will interact in the environment used to generate the series.

    Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety. The International Mineralogical Association (IMA) is the international scientific group that recognises new minerals and new mineral names.

  6. Precious metal - Wikipedia

    en.wikipedia.org/wiki/Precious_metal

    The best known precious metals are the precious coinage metals, which are gold and silver. Although both have industrial uses, they are better known for their uses in art , jewelry , and coinage. Other precious metals include the platinum group metals: ruthenium , rhodium , palladium , osmium , iridium , and platinum , of which platinum is the ...

    This list includes those recognised minerals beginning with the letter A.The International Mineralogical Association is the international group that recognises new minerals and new mineral names; however, minerals discovered before 1959 did not go through the official naming procedure, although some minerals published previously have been either confirmed or discredited since that date.

  8. Properties of metals, metalloids and nonmetals - Wikipedia

    en.wikipedia.org/wiki/Properties_of_metals...

    The chemical elements can be broadly divided into metals, metalloids, and nonmetals according to their shared physical and chemical properties.All elemental metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form alloys with other metallic elements; and have at least one basic oxide.

  9. Native element mineral - Wikipedia

    en.wikipedia.org/wiki/Native_element_mineral

    Native element minerals are those elements that occur in nature in uncombined form with a distinct mineral structure. The elemental class includes metals, intermetallic compounds, alloys, metalloids, and nonmetals. The Nickel–Strunz classification system also includes the naturally occurring phosphides, silicides, nitrides, carbides, and ...
